CYCLONE DUST COLLECTOR.

Application filed October 11, 1922. Serial No. 593,820.

To all whom it may concern:

Be it. known that I, HERMANN KLUG, a citizen of the Republic of Germany,and resident of Bc-rlin-Hermsdorf, Germany, have invented certain newand useful Improvements in Cyclone Dust Collectors, of which thefollowing is a clear, true, and exact specification, reference being badto the accompanying drawing.

l leretofore, all dust collectors operating on the cyclone principlehave been generally cylindrically, that is, circular in transverse crosssection. cyclone dust collector is the most simple used, with a workingcoefficient of 80' to 85%, according to the character of the dust. Inany event, the cyclone dust collector is most generally used.

A chief object of the invention is to improve upon present-day cyclonedust collectors; and with this end in view, a feature of the inventionresides in substituting for the cylindrical casing heretofore in use(generally of sheet iron), a casing of any material whatever (iron,wood,-masonry, etc.), with square or rectangular cross section.

Among the advantages of the present invention, the space for the cyclonepath is utilized to a far greater extent, as it is square or rectangularcross section. Apart from this, the dead corners, which are alwayspresent in cyclones, may, according to the present invention, beutilized ,to advanta e and with technically good effect.

It 1s furthermore possible to make the new construction ofmasonry, orother much cheaper material than the expensive sheet Finally, theoperation is much'less noisy, as the noise caused by heavy materials,such as shavings and the like, falling against the sheet metal walls iseliminated.

ltn the drawings, Fig. 1 is an elevation showing the air or gas inletopening. Fig. 2 a horizontal section through Fig. 1; and

Fig. 3 is a vertical section, showing the filter for fine dust.

Dust-laden air or other gas is adapted to It is well known that the tothe direction of travel of the entering air or other gas. I The battlewall is disposed in the horizontal plane of the inlet opening b, nearthe said one wall, and is adapted to cause the entering current ofdust-laden air'to deviate its course. The casing a is polygonal in crosssection, preferably square or rectangular, or some other polygon havinga relativelysmall number of sides. The interior of the casing, near thebattle plate, is unobstructed in the horizontal plane, so as to permit acircular movement of the dust-laden air, as shown by the arrows, in apath determined by the angular position of the bathe late. The dead.corners, during the whirling of the dust-laden air, prove particularlyeffective separators for the dust from the dust-laden air. Theireliicacy may be considerably enhanced by built-in walls or catch plates6 that extend from the cor- 4 ners inward towards thewhirling dustladenair. The catch plates 6 make it certain that the dust thrown againstthem shall be directed towards the calm regions of the dead corners.

Should it be desired to purify the gas,

the cover 9 of the rectangular or square dust tion, a substantiallyvertically disposed casing polygonal in cross section, the polygonhavingarelatively small number of sides, the casing having an inletopenin through which dust-laden air or other gas is adapted to enter thecasing, and a battle plate disposed within the casing near the inletopening at an angle to the direction of travel of the entering gas, thebattle plate being adapted to deviate the path of the entering gas, theinterior portion of the casing near the baffle plate being unobstructedfrom the center of the casing to the sides thereof so as topermit thegas to whirl therein in a path determined by the angular position of thebattle plate, dust being adapted to be removed from the whirlingdust-laden gas at the corners of the casing, and the gas being thenadapted to travel to the upper portion of the casing.

2. A dust collector having, in combination, a substantially verticallydisposed cas- Eli ing of square or rectangular cross section, one of thewalls of the casing being provided near a corner of the casing with arelatively small inlet opening through which dustladen air or other gasis adapted to enter the casing, and a baflle plate substantiallyvertically disposed within the casing near to and substantially in ahorizontal plane with the inlet opening near a wall adjacent to the saidone wall at an angle to the direction of travel of the entering gas, thebafile plate being adapted to deviate the path of the entering gas, theinterior portion of the casing in substantially the horizontal plane ofthe inlet opening and the baffle plate being unobstructed from thecenter of the casing to the sides thereof so as to permit the gas towhirl therein in a path determined by the angular position of the baflleplate, the angular position of the bafiie plate being adjustable toadjust the path of travel of the whirling gas, dust being adapted to beremoved from the whirling dust-laden gas at the corners of the casing,and the gas being then adapted to travel to the upper portion of thecasing.

3. A dust collector having, in combination, a substantially verticallydisposed casing polygonal in cross section, the polygon having arelatively small number of sides,

the casing having an inlet opening through which dust-laden air or othergas is adapted to enter the casing, a baffle plate disposed within thecasing near theinlet opening at an angle to the direction oftravel ofthe entering gas, the baffle plate being'adapted to deviate the path ofthe entering gas, the interior portion of the casing near the baffleplate being unobstructed from the center of the casing to the sidesthereof, so as to permit therefrom,

the gas to Whirl therein in a path determined by the angular position ofthe bafile plate, and catch plates at the corners of the casingextending from the corners inward towards the whirling dust-laden air toremove dust the gas being then adapted to travel to the upper portion ofthe casing, and the removed dust being adapted to fall to the lowerportion of the casing.

4. A dust collector having, in combination, a substantially verticallydisposed casing polygonal in cross section, the polygon havmg arelatively small number of sides, the cas ng having an inlet openingthrough which dust-laden air or other gas is adapted to enter thecasing, a bafiie plate disposed Within the casing near the inlet openingat an angle to the direction of travel of the entering gas, the baflieplate being adapted to deviate the path of the entering gas, theinterior portion of the casing near the baffle plate being unobstructedfrom the center of the casing to the sides thereof so as to permit thegas to whirl therein in a path determined by the angular position of thebafiie plate, dust being adapted to be removed from the whirlingdust-laden air at the corners of the casing, and the gas being thenadapted to travel to the upper portion of the casing, and one or morefine-filtering layers in the upper portion of the casing for purifyingthe gas as the gas travels upward, the fine-filtering layers beingadapted to be cleaned from time to time.

In testimony whereof I herewith afiix my signature in presence of twowitnesses.
